To all when] it may concern.-

Be it known that I, WIL LBURN B. BIRMING- HAM, a citizen of the United States, and a resident ol? Raleigh, county of X'Vake, State of North Caroliira, have invented an lmprove- 1 ment in Fillingdteplenishing Meol'ianism for Looms, of which the followin description,

in connection with the accompanying; dra. ing, is a specification, like letters on the drawing repre f l like parts.

This in ing-replenic such as shov moms of the N orthrcp type, 1 United States Patent No.

529,940, wherein a filling carrier or bobbin is at the proper time transferred automatically from a ill eder to the shuttle; and my invention has l -or its object the production 1 ol a novel combined supporting and guiding device or liufier to cooperate with a filling carrier when transierred.

riers and transfer them to the running-sl1uttle S, and the fixed wall or abutment h on the stand forming one side of a dischargel throat, maybe and are all of well-known construction.

As will be understood by ll'iose familiar with the Northrop type cl loom the abu1- ment h directs or guides one side of the head of a filling-carrier as the head when transferred passes through the throat.

Opposite the abutment and forming the opposite side of the throat is a yicldiuglycontrolled buffer which cooperates with and guides and supports the adjacent side of a filling-carrier head when transferred, and in my present invention such butler is mounted to swing on a fixed fulcrum located at a (liS- tance above and back of the bull'er for a Durpose to be explained.

particularly to lilla side elevation and partial transverse section of a portion of the filling- Fig. 2 is an inner side eleva Herein the butler 1 is shown as a fiat but inclined or beveledcxtremity or foot formed on the end of an extension 2, projecting rigidly from the lower end of-an elongated arm 3, the latter and its extension 2 forming a substantially L-shaped support for the j butler. At its upper end the arm has a 1; lateral hub 4 on the faceopposite that from l which the extension 2 projects, the hub are l waiving loosely a fulcrum stud or pin fixcdly held in the stand A and projecting h'orizontally from the inner side thereof. Such fulcrum-pin is located at a distance above both the abutment k and the buffer and well behind them, as herein shown, so that the n'iovcment of the buffer toward and from the abutment will be in a short arid relatively llat arc. This will be manifest l by comparing the full and dotted line positions of the buffer in Fig. 1.

As shown, the arm 31's located adjacent the inner side of the feeder-stand A, and the exj tension 2 is laterally o'll'set from the arm at 6,

Fig. 3, to permit said extension to lie adjacent the outer side of the stand, with the butler 1 opposite the abutment. The stand is cut away to leave a shoulder 7, which serves as a stop for the bullensupport, the ofifset 6 when resting against the shoulder limiting movement of the bufier toward the abutment. A tubular spring seat or pocket #3 formed on the arm 3 to receive one end of a spring 9, the other end resting against a lug l (l on the stand, (see Fig. 2,) the spring normally acting to yieldingly press the buffer toward the abutment h. i

The boiler and its L-shaped support are conveniently made as a casting, the buffer thereby being rigid on the support.

As shown in Fig. 1. by full lines, the normal position of the butler is in a plane opposite and inclined with relation to the abutment, the buffer extending son'iewhat beneath the head of the filling-carrier b next to be translcrred, thereby assisting; in supporting the filling-carrier. When the transferrerj" acts to force the latter downward, the head passes down between the abutment and butler, sliding along the inclined lacc thereof and movinp it rearwardly against the action of spring 9 away from the abutment h to thereby widen the throat sulliciently for the head of the filling-carrier to pass therethrough.-

, Such movement of the buiier is in a circular are havin the fulcrum as a center; but as l ward the abutment, said bul'l'er forming the the fulcrum is such a distance above the buffer and back of it andv as the widening of the throat is comparatively small the arc of movement of the buffer will be quite fiat. Consequently while the buffer is moved out of theway of the filling-carrier head it cannot descend far enough to by any possibility come into engagement with the shuttle or the shuttle-box as the lay swings up and back.

The spring 9 returns the buffer to operative position as soon as the head of the filling-mm rier has passed the-lower edge of the buffer,

the latter cooperating with the head until the same is wellinto the shuttle. While the buffer is thus arranged to approach the shuttle .very closely when transfer is effected, it cannot gofar enough to'engage' the shuttle, so

that all liability of smashing the shuttle or the replenishing mechanism from such engagement is obviated.

The form of, buffer shown is very strong and durable; and it is easily and cheaply made. I a

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is- 4 I 1. The combination, with a feeder to hold a plurality of filling-carriers, and a trans- 'ferrer, of a fixed abutment forming one side of adischarge-throat through which the head of a fillin -carrier asses when transferred from the eeder, a ufier to cooperate with and guide and sup ort the opposite side of the head of the ill ing-carrier, a depending arm on the lower end of which the buffer is mounted, a fixed fulcrum at the upper endof and on which the arm swings toward and from the abutment, and a spring to act upon the arm and normally retain the buffer in op- I erative position.

2. The combination, with a feeder to hold a plurality "of filling-carriers, and a trans ferrer, of a fixed abutment to cooperate with and guide one side of the head of a filling-carrier when transferred, a buffer to cooperate with the op osite side of the head, supportving and gui ing the same, an elongated substantially L-shaped support on the lower end of, which the buffer is mounted, a fixed fulcrum for the upper end of and on which the support swings toward and from the abutment, and means to yieldingly press the support toward the abutment and maintain the utter operative. v V 3. The combination, with anintermittingly- .rotatable feeder to holda plurality of fillingcarriers, a stand on which it is mounted, and

, a transferrer, of a fixed abutment forming one side of a discharge-throat for a filling-carrier. when transferred, an oppositely-located buffer fulcrumed on the stand above and. back of the abutment, a spring to yieldingly move the buffer into operative osition, and a stop to limit movement of t e buffer toother side of the discharge-throat. 4. The combination, with anintermittinglyrotatable feeder to hold a plurality of filling-' carriers, a stand on which it is mounted, and

a transferrer, of a fixed abutment forming oneside of a discharge-throat for a filling-carrier when transferred, an oppositely-located buffer forming the other side of the throat, a depending arm fulcrumed at its upper end on the stand and having a rigid forward'extension at its lower end .on which the buffer is mounted, and a spring to act upon the arm and normally position the buffer.

5. The combination, with a feeder to hold a plurality of filling-carriers, and a transferrer, of a fixed abutment forming one side of a discharge-throat through which the head i of a filling-carrier passes when transferred from the feeder, a depending L-shaped support having a fixed fulcrum above and back of the abutment, a spring to press the support toward the abutment, and an inclined uffer on the lower end of the support oppo- I buffer opposite the abutment, a buffer-sun port rigidly connected with the buffer and upturned above it, and a fulcrum for and on which the upper end of the buffer-support is pivotally mounted.

7. A support and guide for a filling-carrier in filling-replenishing mechanism for looms, consistingof an L-shaped support having a fulcrum-hub at its upper end and an inclined" or beveled foot at itslower end, a spring-seat on the support, and a fixed fulcrum on which the fulcrum-hub is loosely mounted.

8. Thecombination, with a filling-feeder, of a discharge-throat therefor having a fixed side, a spring-controlled buffer forming the opposite side and movable toward and from the fixed side a fixed fulcrum loeated'at a distance above and back'of the buffer and upon which it is movable and a stop to limitmovement of the buffer toward the fixed side of the throat. l

9. An L-shaped support for a filling-carrier in filling-replenishing mechanism for looms, pivoted and sustained at its upper end only and having a beveled foot at its lower WILLBURN B. BIRMINGHAM Witnesses:
